In a local bar, a customer slides an empty beer mugdown the counter for a refill. The bartender is momentarily distracted and does not see the mug, which slidesoff the counter and strikes the floor at distance d fromthe base of the counter. If the height of the counter is h,(a) with what velocity did the mug leave the counterand (b) what was the direction of the mug’s velocity justbefore it hit the floor?
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
